We have a store loaction that has a Partner ACS R7 with a 308EC and 400E card in a 5 slot carrier. About a month ago they reported that while they were talking to a customer on one of the phone lines(POTS) they could hear ringing in the background and another call would cut into the line and the original party that was call is lost and we are talking to the party that rang in on the line. This has been happening periodically. So we had a tech go out to the site from the Telco - AT&T (ameritech) and they advise the problem was with our Phone equipment. So we hired a tech to go out a clean up the DMARC to our Phone system and make sure not lines were crossed punched on the same pair - nothing was. About a week later the problem happened again. AT&T still says it is our phone system and they test all the lines fine - Site has 8 lines and it happens on Line 1 and 2. This site only has a hunt group for features on the lines.

Can anyone what next steps can be taken with the LEC or where to have them look for the issue??

Thanks,

Try connecting a single line telephone to each line (at the LEC demarc) and try to duplicate the problem.

There could be a wiring issue upstream.

I can almost surely say it's not a system otherwise it would happened every time line 2 is cutting off callers on line 1 during an incoming ring. It might happened during bad weather on outside D-mark if there is slight ground on either line. That issue required thorough Troubleshooting and analysis. If line crossed you would hear double dial tone. If it is the ACS then you will hear each others every time you are using Lines 1 & 2. If it neither one it something at CO or D- mark.

Allow me to recommend a very POSITIVE test.

Swap lines 1 & 2 with lines 7 & 8, and see if the trouble stays with the PARTNER PORTS or the CO Lines.

It shouldn't take long to figure it out.

IT WILL TAKE LONG to convince the provider if it is their problem.

I had to do this twice at one location 'cause one of the Night Managers at the restaurant I did this at took it on himself to swap them back before we could get results.

So warn everyone to LEAVE THE PHONE SYSTEM ALONE while you are testing this.

Good Luck!
